Never use a foreign phrase, a scientific word, or a jargon word if you can think of an everyday English equivalent.

Break any of these rules sooner than say anything outright barbarous.

These rules are absolutely essential for good system or application security. All too often we have the situation where the real target is to provide an insecure system and it is obfuscated by the use of this “political language”. To turn the words of Orwell to our subject, the great enemy of software security is insincerity. When there is a gap between one’s real and one’s declared aims, one does not get proper security.
